Inorganic mineral fiber spray rock mortar and using method thereof

Abstract

The invention belongs to the field of wall building construction inside and outside heat insulation, sound insulation and fireproof materials, and relates to inorganic mineral fiber spray rock mortar and a using method thereof. The inorganic mineral fiber spray rock mortar is prepared from, by weight, 60-65% of inorganic mineral fiber, 15-20% of fibrous sepiolite, 0.1-0.5% of hydroxypropyl methyl cellulose, 2% of redispersible latex powder, 0.5% of water repellent and 10-16% of Portland cement. The using method includes the steps that water is added into the inorganic mineral fiber spray rock mortar according to the weight ratio, the mixture is stirred into paste, and the paste is put into a sprayer for spraying; a wall is directly sprayed, inorganic mineral fiber spray rock mortar layers are formed at the two sides of the wall until the layers reach the design thickness; the surfaces of the inorganic mineral fiber spray rock mortar layers are decorated; compared with an existing inorganic mineral fiber spray heat insulation wall construction, A1-grade fire resistance is higher, sturdiness and weather fastness are better, and the defect that an existing inorganic mineral fiber spray heat insulation material has the single purpose of heat insulation in an outer curtain wall and a stone wall is solved.

Description

technical field [0001] The invention belongs to the field of thermal insulation, sound insulation and fireproof materials for inside and outside wall building structures. In particular, it relates to an inorganic mineral fiber spraying rock mud and its application method. Background technique [0002] At present, the inorganic fiber spraying in my country's construction market is to mix inorganic fiber cotton with a special water-based binder for spraying construction. The biggest shortcoming of its material products is that the water-based colloidal binder mixed material has poor UV resistance and short service life. , can only be used for curtain wall or stone wall insulation, material application has limitations. [0003] The invention provides a method for preparing inorganic mineral fiber sprayed rock mud material. The inorganic mineral fiber sprayed rock mud has excellent thermal insulation performance and can be used as a wall insulation layer. The sprayed material is...

[0002] At present, the inorganic fiber spraying in my country's construction market is to mix inorganic fiber cotton with a special water-based binder for spraying construction. The biggest shortcoming of its material products is that the water-based colloidal binder mixed material has poor UV resistance and short service life. , can only be used for curtain wall or stone wall insulation, material application has limitations

[0003] The invention provides a preparation method of inorganic mineral fiber sprayed rock mud material. The inorganic mineral fiber sprayed rock mud has excellent thermal insulation performance and can be used as a wall insulation layer. The sprayed material is sprayed on any complex building wall by special equipment On the surface, it forms a seamless mesh multi-dimensional structure with random fibers, which fundamentally solves many shortcomings of traditional thermal insulation materials such as many seams and poor airtightness, thereby enhancing the overall thermal insulation performance of the thermal insulation wall building structure
